The building in Grand Junction exists as the Dalby-Wendland CPA building. Coin is about the size of a 50 cent piece.   Based on the now relatively small capital investment amount of $125,000. it would appear the token was probably issued in the 1930-40s.  

During the Fall of 2022 I will be reducing my collection of Grand Junction and Colorado books and items, please see my other listings.

Text me if any questions.
